Genetic dissection of QTLs for yield traits were further conducted for the genomic regions harboring Pi25. It was found that two or more linked QTLs for yield traits were located in this region, and they had effects on each of the 6 yield traits studied. It remains unclear that the genetic drag between Pi25 and yield QTLs was solely resulted from unfavorable linkages, or partially ascribed to pleiotropism of Pi25.
